Product features: 1. Can meet electrical parameters such as high power (1KW to 10MW per unit), high voltage (commonly AC 110V to 690V), or high current (up to 10000A per unit). two According to the needs, we can design adjustable gears, configure intelligent digital displays, and implement various protection measures (such as over temperature protection, over current and over voltage protection, sound and light alarm devices). In addition, our water-cooled resistance boxes/cabinets can also be equipped with cooling systems and water towers to fully meet the personalized needs of customers.

When a single resistor cannot meet its load requirements, multiple resistors are combined in series and parallel to increase power to meet the requirements.

2) The load is cooled by the axial flow fan through circulating cooling of the internal load resistance.

3) The types of built-in resistors in the load include high-power wound resistors, aluminum shell resistors, high-energy resistors, plate resistors, stainless steel resistors, and high-voltage resistors.

3. Precautions for using loads:

1) There shall be no flammable, explosive or corrosive media within the installation range.

2) Connect the load and instrument power supply according to the markings on the equipment panel. After confirming that the voltage is normal, turn on the instrument power switch on the cabinet. At this time, all instruments display "O" and all fans are running normally. Connect the load power supply (all fans can only be powered on before connecting the load power supply).

3) For safety reasons, please do not touch the surface of the cabinet (excluding the panel) during equipment operation to prevent burns.

4) After the equipment stops working, please wait for 30 minutes before turning off the fan power to avoid high temperature accumulation and damage to other components (such as instruments, switches, etc.)

5) If there is mild smoke during the first use of the load, it is a normal phenomenon that the resistance encapsulated silicone resin evaporates when exposed to high-temperature media.

4. Application areas:

Generator testing, power equipment, battery testing, frequency sensors, elevators, sub arc welding machines, lifting machinery, construction machinery, ships, rolling mills, wire drawing machines, high-speed machines, UPS power supplies, pulse load applications, hoists, generators, transformers, starting, braking, speed regulation and load testing, as well as medical, railway, automotive, military and industrial control environments, etc
